NOTE

I wish to express my sincere thanks to all my Professors, but especially to Professors Starr W. Cutting, Martin Schütze, and Francis A. Wood, under whom the major portion of my work in the Graduate School has been pursued.

This particular study, however, is the outcome of interest awakened by Professor Schütze while I was a member of his seminars.

I owe a special debt of gratitude to him, not only for his guidance in this endeavor, but for the inspiration and encouragement which has come to me from the very beginning of my work under him.

Georgiana R. Simpson
